IMHO, because the class from PEAR actually putting out an image, it
ultimately behaves as an image contenttype=image/png (or something like
that).
So in order to have 2 or more barcodes on your page, or text, you chould
write another php (even html) that utilizes that your current barcode
script.
Example:
create-barcode.php
<?php
require("Image/Barcode.php");
$bc = new Image_Barcode;
$bc->draw($_REQUEST['param1'], $_REQUEST['param2'], "png");
?>
index.html
<html>
<!-- This is the first barcode -->
<img src="create-barcode.php?param1=BE1029¶m2=Code39" />
<!-- This is the second barcode -->
<img src="create-barcode.php?param1=BE1020¶m2=Code39" />
<!-- This is just text -->
Hello
</html>
PLEASE NOTE: That the script that i put there is just an example of how
it can be done, without the consideration of other security measures.
